Our take on the Flex Seal Sealant, 2 lb, Gray, Case of 6

Flex Seal is a rubberized liquid coating that sprays or brushes on to seal leaks, cracks and holes on roofs, gutters, pipes, foundations and other surfaces. The gray formula dries to a rubbery, watertight layer that stays flexible. This listing is a case of six 2 lb cans, aimed at bigger jobs or repeat use. At $24.93 for the case at eBay as of November 4, 2026, it is the only new price shown across two stores, so there is little range to compare against.

Questions and answers

Is Flex Seal worth it for roof leaks?
Yes for small cracks, seams and flashing where a flexible coating can bridge the gap. For large holes or active structural leaks, use a proper patch or call a roofer.
How is this different from Flex Seal Spray?
This is the 2 lb brush-on liquid can, which gives thicker coverage on flat surfaces. The spray version reaches awkward spots but lays down a thinner coat.
How much area does one 2 lb can cover?
Coverage depends on surface and thickness, but a 2 lb can typically handles small repairs and touch-ups rather than a whole roof. The six-can case suits several jobs.
What surfaces can I use it on?
It bonds to metal, wood, concrete, masonry, glass and most plastics. Clean and dry the surface first, and avoid use on surfaces that stay submerged or under constant pressure.
How should I store the cans after opening?
Seal the lid tightly and store the can upright in a cool, dry place. Wipe the rim clean before closing so the lid does not stick.
When is the best time to buy the case?
The case was $24.93 at eBay as of November 4, 2026, with only two stores listing it new. Watch for seasonal roofing and gutter sales in spring and fall.
